DRAM will annotate input predicted coding sequences from microbial genomes (KBase genome objects) and provide genome metabolic summaries. DRAM is most useful for annotating genome sets, where the DRAM product can be used to compare the metabolic profiles of each genome.

DRAM for genomes works by annotating all genes given in a KBase Genome object with a set of databases curated to the task. The user is given a tab delimited annotations file with all annotations from all databases for all genes. Additionally, the user is given a folder with annotated nucleotide and amino acid fasta files of all genes. The results of annotation are distilled to generate three files: 1. The genome statistics table, which includes all statistics required by MIMAG, 2. The metabolism summary, which gives gene counts of functional genes across a wide variety of metabolisms and 3. the product, an interactive heatmap showing coverage of modules, the coverage of electron transport chain components and the presence of selected metabolic functions.
